Some tips (I write on/off for such mags):
* Give them a deadline to reply by - otherwise they could take ages to get back to you. Set it for 2 weeks. After 7 days send a follow up email.
* Ensure you tell them you want "reprint content permission" which will let you publish it on your blog or elsewhere after they publish it (usually the grace period is a month afterwards).
* 5p per word is minimum price for articles under 5000 words - if they offer you less haggle :) (the most I get under 5000 is 7p a word, above 5000 words it will be done on fixed rates depending on the mag & the content)
* They will try to bully you gently - stand up strong. It will get you further :)
* Be bold in your initial email (but dont gush, I learnt the hard way the "I love your mag" doesnt work with editors because they dont love it, it is their job :D). Include anything that qualifies you as an expert.
* Link to previous work that has gone down well (if there is any) and also link to obviosuly respected industry experts with similar views (so they know your not just an upstart :)).
Good luck!
If you mean "made public", just put it on your blog. (If you don't have one, make one-- there's a zillion free services.)
Or are you looking for a publisher to edit it and pay you for it? If so, you're pretty much out of luck-- the fact that you wrote it without a market in mind is a good indicator that it's not ready for that type of publication.
EDIT: ok so it's clear now the intent isnt commerical :) so that is a moot point I just made!
